Description

The PIENU experiment was performed to measure the ${\pi}^+{\to}e^+{\nu}_e$ branching ratio with precision of $<0.1$% and search for rare pion decays. Recently many new and improved results of the rare decay searches involving heavy neutrinos ${\pi}^+{\to}l^+{\nu}_H(l=e,{\mu})$, weakly interacting neutral bosons ${\pi}^+{\to}l^+{\nu}X$, and three neutrinos ${\pi}^+{\to}l^+{\nu}_l{\nu}\bar{\nu}$ have been obtained. Search for exotic muon decay ${\mu}^+{\to}e^+X$ was also performed. Results of the searches will be presented.
